Q:What's the advantage of using an electric ball valve?
Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.
Q:Hello, I would like to ask the household tap water valve selection of stainless steel ball valve or brass ball valve is better, thank you
I have used two kinds, but stainless steel gate valve is better. Note that it must be made of stainless steel 304. I bought more than 300 yuan a gate valve. Total valve, no way to save money.
Q:What are the differences between the lever ball valve and the handwheel ball valve? What are their differences?
Group pairs of valves, have not heard of a lever type ball valve, only lever type safety valve, hand wheel type is only the way it drives different, the way is also ever-changing, to see the needs of individuals
Q:The valve nominal 1/2, 3/4 is how much?
1/2 equivalent to the national standard of 15mm, 3/4 equivalent to GB 20mm. That is, DN15 and DN20
Q:What are the applicable conditions of ball valves?
This deformation can compensate the ball manufacturing accuracy and surface roughness, and ensure the sealing performance of the ball valve.Because the valve seat ring is usually made of plastic, so the choice of valve structure and performance, to consider the ball of fire and fire, especially in petroleum, chemical, metallurgy and other departments, the use of ball valve in the equipment and piping system of flammable and explosive medium, should pay attention to fire and fire.Usually, the double adjustment, strict sealing, slurry wear necking channel, the rapid opening and closing movement (1/4 turn open and close), high pressure cut-off (pressure difference), low noise, there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere,It is recommended that ball valves be used in piping systems with small operating torque and low fluid resistance.
Q:The difference between cut-off valve and ball valve in PPR
Yes, now the globe valve is more than the ball valve with more people, and its main or cut-off valve, a lot of adjustability, and most can be universal.Specific differences are as follows:Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.The cut-off valve is a forced seal type valve, so when the valve is closed, the valve must be applied to the pressure, to force the sealing surface is not leaking. When the medium into the valve six from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault. In recent years, the emergence of self sealing valve, globe valve replaced by medium flow on the top of the valve into the valve chamber, then in the medium under pressure, the valve off a small force, and force open the valve, stem diameter can be reduced accordingly. At the same time, in the role of media, this form of valve is also more stringent. China's valve "three to" has stipulated that the flow direction of the cut-off valve should be top-down.
Q:What valve is this valve, please? Ball valve?
This is a manual ball valve three simple when meet your requirements is L ball valve
Q:Ball valve Q41f and Q11f difference, whether universal?
Q41 is flanged ball valve, Q11 is a threaded ball valve, the two connections in different forms, is not universal
Q:Copper ball Q11F-20T is what mean?
Q ball valve1 internal thread1 throughF PTFE soft seal20=20PA=2.0mpa pressureT copper material
Q:Q41F-16-64P this is the ball valve, what type, please answer in detail, thank you!
Q--- ball valve4---- flange connection1----- ball valve is floating ball (ball valve has floating ball and fixed ball points, 7 represents the fixed ball)F----PTFE- PTFE seal (PTFE PTFE),16-64---- ball valve nominal pressure is 16-64 kg (1.6-6.4Mpa)P---- ball valve body material is 304 stainless steel
